Chemical fabrication of ultrahigh-density arrays of nanopores

from the go-self-assembly dept.
Senior Associate MarkMuhlestein writes "This looks like interesting work, reported in the Dec 15 Science. If you have access, the entire article is at http://www.sciencemag.org/cgi/content/full/290/5499/2126 Here's the abstract: Science, 290, 2126 (15 Dec 2000) 'We show a simple, robust, chemical route to the fabrication of ultrahigh-density arrays of nanopores with high aspect ratios using the equilibrium self-assembled morphology of asymmetric diblock copolymers. The dimensions and lateral density of the array are determined by segmental interactions and the copolymer molecular weight. Through direct current electrodeposition, we fabricated vertical arrays of nanowires with densities in excess of 1.9 x 10^11 wires per square centimeter. We found markedly enhanced coercivities with ferromagnetic cobalt nanowires that point toward a route to ultrahigh-density storage media. The copolymer approach described is practical, parallel, compatible with current lithographic processes, and amenable to multilayered device fabrication.'

On ethics: engineers compared to programmers

from the is-there-a-programmers-code-of-ethics dept.
An engineer points out that the engineering professions have codes of ethics that guide them in designing for safety and in communicating with the public, and that these are not being followed by some programmers: "It seems to me that as a nanomechanical engineer (or rather a mechanical engineer with an interest in nanomechanics), I was permanently "conditioned" to always think of the ethics behind a design by "upping the safety factor" on my design. If your daily dealing with deadly machines — or rather machines that can cause harm to the public — then as an engineer I am obligated to design something that has a higher safety factor than someone who designs air conditioning systems. This fact, or rather a standard rule of engineering practice, has been overlooked by Joy and his counterparts…My point is this, that as a general rule engineers create highly reliable systems that must have a certain safety factor included whenever there is the slightest chance of harm to the public. I, or rather we, as engineers (Civil, mechanical, (High power) Electrical), are always worried about the safety factors we have set on a design…I think I might be over simplifying the issue but ultimately I have a hard time understanding why so many programmers are a) claiming to have a solid understanding of safety factors when their job has only a few instances for life or death of the public and b), if they follow the same code of ethics set forth by the state governmental systems, why is it they are not lumped together with the rest of the classically trained engineers? One other thing, if they are, then didn't they see that part in the ethics section about slandering or speaking out to the public on something in which they have no educated knowledge?… I would love to hear what the software "engineers" have to say about this particular essay in order for me to learn more about their trade."

Engineers seen as unable to make moral decisions

from the who-else-is-even-paying-attention? dept.
From a Newsweek article on MSNBC on the coming age of cyborgs: "Who, then, can speak on moral issues? Certainly not the engineers. Ellen Ullman, a former computer programmer and the author of the 1997 book Close to the Machine: Technology and Its Discontents, says that 'the problem is not the technology, which in any event canít be stopped. The problem is that engineers are making decisions for the rest of us.' Programmers are hired guns, she says, and rarely understand in a nuanced way their clientsí actual work. They are, she says, the last people 'to understand what is an acceptable risk.' " CP: In Foresight's experience, programmers and engineers are far more attentive to ethical issues in technology than members of other professions.

Nanotech prospect affecting business decisions

from the waves-of-the-future? dept.
The prospect of nanotech is already affecting real-world business decisions, as reported by Reuters on Yahoo about the company KPNQwest NV, the Dutch-American data communications company: "President and Chief Executive Jack McMaster said nanotechnology meant the company may be able to pack so much more processing power into each 10,000 square meter center that it could build fewer. That would save it a fortune, as each center costs more than 50 million euros ($44.48 million) to build…'I've begun to rethink my position only because of the implications of nanotechnology,' he said. 'The amount of computing power that's going to occupy a square meter could be four, five, six times what we initially thought.' "

Nanotech action figure wins big: $100 million

from the at-least-it's-Max-not-Joe dept.
PR News on Yahoo reports that a nanotech "action figure" [read: doll for boys] is a big hit: " 'All factors indicate that by year-end Max Steel will exceed a $100 million brand worldwide in its first year,' said Matt Bousquette, president of Mattel's Boys/Entertainment division. 'And, that the product line will be a complete sell-out by Christmas in various countries'…Max Steel is a unique aspirational character that kids can identify with and the innovative 12-inch scale appeals to boys four years old and up. Josh McGrath is a cool college student and action sports athlete who is accidentally infused with nanotechnology (N-Tek(TM)) giving him super human abilities and turning him into Max Steel." CP: "Aspirational" is right, and those aspirations just might work out.

Fictional polymaths debate destructive nanotech

from the that's-a-long-time-from-now dept.
Found by GoTo.com: The essay The World in 2050 by Yale lecturer Nick Bostrom features an imaginary dialogue, set in 2050 and broadcast in virtual reality, in which three polymaths debate various issues, especially risk of destructive nanotechnology. The discussion closes with: "We need greater-than-human intelligence to build defenses against nano-attacks. We would not reduce the danger by slowing down; on the contrary, that would make the risks even bigger. The best we can do is to press onward with all possible speed, using as much foresight as we can muster, and hope that there is an other side that we can get to."
